Before you proceed with the OpenStack packages update, verify the following:

  • Upgrade of MCP is done to the latest Build ID. Verify that you have updated DriveTrain including Aptly, Gerrit, Jenkins, Reclass, Salt formulas, and their subcomponents to the current MCP release version. Otherwise, the current MCP product documentation is not applicable to your MCP deployment.
  • All OpenStack formulas states such as nova, neutron, and so on can be launched without errors.
  • (Optional) Online dbsyncs for services are performed before the update maintenance window since this task can take a significant amount of time.
  • No failed OpenStack services or nodes are present in the cloud.
  • Utilization of the disk space is up to 80% on each target node, which include the ctl*, prx*, gtw*, and cmp* nodes.
  • There is enough disk space on the node that will store the backups for the MySQL databases and the existing cluster model.
